Specification of Letters Patent.

Application filed. April 26, 1921. Serial No. 464,765.

. To all whom it may concern:

Beit known that I, HENRY S. BREWING- TON, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Paper Containers, of which the following is a specification.

This invention relates to receptacles which are constructed of paper, pasteboard or analogous material, and more particularly to receptacles of this kind which are cylin-' drical in shape.

The invention has for its object to provide novel and improved closures for the ends of the receptacle, the same consisting in a combination and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification, and in said drawing Figure 1 is a central vertical section of the receptacle r Fig. 2 is a plan view thereof, and

Fig. 3 is a vertical section of the bottom portion of a receptacle showing a modified structure.

Referring specifically to thedrawing, 5 denotes the cylindrical wall of the receptacle, the same being provided with end closures in the form of disks 6 and 7, respectively, the former being at the top and the latter at the bottom. These disks may be made of the same material as that of which the cylinder 5 is made.

To the top of the cylinder 5, on the outside thereof, is permanently secured by any suitable means, an encircling band or ring 8 composed of the same material as that of the cylinder. This band projects a short distance above t-ht top edge of the cylinder so that it may enclose the disk 6, the latter seating on the top edge of the cylinder. The structure results in an annular shoulder inside the cylinder, said shoulder forming a seat for the disk 6.

In order to secure the disk 6 in place and also to seal the same, there is folded over the top edge of the band 8 a rigid sheet metal ring 9 which extends downwardly inside the band, in contact with the inner surface there of, as shown at 10, and has adjacent to the top of the disk an inturned flange -11, said 't-heinner surface of the band 8, and the flange 11 is tightly pressed down against the marginal port-ion of the disk 6, in view of which it will be evident that the disk is securely held in place, and also sealed to prevent leakage of the contents of the receptacle if such contents are of a liquid nature. The ring can be spun on or applied in any other approved manner, and the structure is very simple and cheap, and

' readily assembled.

The bottom disk 7 is secured and sealed in the same manner as the top disk 6. However, the sealing and securing ring 12 is clamped over the bottom edge of the cylinder 5, and has a portion 18 extending upwardly thereinto in contact with the inner surface thereof, and terminatin in an inturned annular flange 14 on WlllCh the disk 7 seats.

Fig. 3 shows a modified bottom disk 7 the same having its marginal portion slightly elevated,'as shown at 7 to form a shoulder 7 located inwardly of the edge of the disk and concentric therewith. The flange 14 engages the bottom of the raised portion 7 b of the disk, and extends inwardly far enough to abut with its edge against the shoulder 7. This structure provides a double seal for the receptacle bottom, and effectually prevents leakage.

The rings 9 .and 12 also act. to reinforce andstifien to body 5 of the receptacle so that it Will retain its cylindrical shape under rough handling, and prevent the top and bottom closures from getting loose to rupture the sealing contact.

I claim:

A paper receptacle comprising a cylindrical body, an end closure for said body comprising-a disk inside the same and having its edge in contact with the inner surface of the body, and a sealing and securing vmember for the disk comprising a rigid metallic ring extending over and secured to the edge of the body, and having an inner portion extending intothe body in intimate contact with its inner surface, said inner portion terminating in an annular flange which engages the disk, and the inner portion and its flange covering the joint between the edge of the disk and the body of the re- 10 v
